Yeah, unlike the chinese chops, these are small. Mine is only one centimeter square, it fits perfectly just under the print and above the mat. Another good thing is that the inks they send you are archival, so your prints wont be harmed. The guy, Ben Falge is really courteous and has great communication with you to help you choose what would be good for you. ALthough the little gizmo is expensive I gotta say the purchasing experience was a pleasure, nice guy, helpful and professional. You can also ask him to add additional stuff to your stamp to make it unique.
